Crane gate valves offer the ultimate in dependable service wherever minimum pressure drop is important. They serve as
efficient stop valves with fluid flow in either direction. Gate valves are best for services that require infrequent valve operation, and
where disc is kept either fully opened or closed. They are not recommended for throttling. With the usual type of gate valve,
close flow regulation is impossible. Velocity of flow against a partly opened disc may cause vibration and chattering and result in
damage to the seating surfaces. Also, when throttled, the disc is subjected to severe wire-drawing erosive effects.

Each valve in this section is classified by its pressure rating. All valves, except clamp gate valves, designated as Class 125 and
250 comply with MSS SP-70 Industry standards Bronze-trimmed valves are recommended for steam, water, air and non-corrosive oil or
gas.
